Even as a US citizen, at this point, it is my policy to never leave the country with a device & set of data that I wouldn't mind losing at customs.<p>Even though I have an essentially absolute right to re-enter the country, my hardware apparently does not, at least without potentially being detained for an extended period.<p>So, burner phone and pre-wiped laptop if I need it, all powered down. If I need any files while away, store them in a secure Box or other account before crossing borders.<p>At this point, it seems like just a necessary evil extra expense in time and money, and a good idea for other countries, although it sadly seems that the US is now the fast follower of Russia, China, etc, in terms of repressive practices.
